HEEL NAILING AND TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 377,577, dated February7, 1888.

Application filed November 10, 1887. Serial No. 254,746. (No model.)

To all whom, it 11mg concern.-

Beit known that I, FREEBoRN F. RAYMOND, 2d, of Newton, in-the county ofMiddlesex and State of Massachusetts, a citizen of the UnitedSta'te's,have invented anew and useful Improvement in Heel Nailing andTrimming Machines, of which the following is afull, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention is an improvement upon that described'in various patentsheretofore granted me in my application for Letters Patent filed April16, 1887, and in the application of O. 0. Small, filed April 19, 1887;and it comprises an automatic heel nailing or attaching machine having anumber of jacks adapted to be brought successively into operativeposition in relation to the heel-attaching devices.

It further relates to the combination of a series or number of jacksmounted upon a common support and adapted to be rotated or turned withsaid support into operative positionwith the heel-blank-attachingdevices and said attaching devices.

It further relates to the'organizat-ion, in an automatic heelattachingmachine,'of a numher or series ofjacks mounted upon a common support andadapted to be rotated in relation to the heel-attaching devices, withsaid heelattaching devices, comprising mechanism for automaticallyfeeding the heel blank and,

.when atop lift is separately fed, the top lift into position forattachment, an automatic nail-supplying mechanism, and a gang or groupof awls and gang or group of drivers,

with or without a heel-breasting device, also automatically brought intoposition and operated.

It further relates to a heel-nailing machine having a number or seriesof jacks each having a movable post, spindle, or support, said movableposts, spindles, or supports and a common head carrying the jacksand'adapted to move the spindles or posts of the respective jacks intooperative position with the attach ing devices.

It further relates to the organization and combination, in aheel-attaching machine, of two or more jacks mounted upon a commonsupport adapted to be moved to bring the jacks into position, theheel-attaching devices, and heel-trimming mechanism.

It further relates to the combination, with heel trimming devices, of aseries of jacks mounted upon a common support and adapted to be moved topresent heels in sucoessiveorder tothe heel-trimming mechanism. 7

It further relates to various features of organization and construction,all of which will hereinafter be explained.

' In the drawings, Figure 1 is a view in front elevation of a machinecontaining the features of my invention. Fig. 2 is a View thereof invertical section. Fig. 3 is a view in plan of the heel-trimming devices.Fig. 4 is a view Fig. 5 is a view a Ais the nail-carrier, which isautomatically moved into and out of position by the cam a upon thevertical shaft a, to carry nails from the automatic nail-supplyingdevices (not shown) to the templet.

B is areciprocating head. I

B is a rotary-head carried by the reciprocating head, and'having the armI) supporting a block having a gang or group of awls, b, an arm, if,having a block carrying a gang or group of drivers, If, an'arm, b, andan arm, b carrying the heel-breasting knife I). This head B" isrotated,.preferably, by means'described in said application of O. 0.Small.

' C is the heel-blank carrier, and Ois the toplift carrier.

0 is the stack of heel-blanks; O, a stack of top lifts; c, theheel-blank transferrer, and'c' the top lift transferred. The heel-blankand top-lift transferrers are operated substantially as described insaid Small application.-

The jacks D are mounted upon the head or support D.

This head or support has horiioo zontal guideways cl for each jack, andit is also provided with a central hole, d, whichj receives thehorizontal post or stud d, with which the head D is adapted to beturned. This post or stud d is supported by and has bearings in theframe or bracket D". (See Figs. 1 and 2.) Each jack D has averticallymovable post, spindle, or support, d which supports the lastor work-support (1*, and each jack is adapted to be moved horizontallyupon the head D when it has been turned or moved to an upright positionas represented in Fig. 1, with the last or jack-support beneath thetemplet A and the spindle or post (I in line with the toggle-head E. Thebase of the jack in this event is supported by the head D and by thetable d which has ways d in extensions or ways cl of the head D. Thehead D and the table d are not required to take any strain. They simplyact to support the jack, the strain of the operation of the machinecoming upon the toggle-head E and the templet A. The head D is lockedautomatically in position, to bring its guideway d in line with theguideway d, by means of the spring registering-pin (l (See Fig. 2.) Thetoggle-head E is made vertically movable by means of the cam 6 upon thevertical shaft a, which has a cam-groove, e". The lever e is pivoted ate, and has a cam-pin that enters the cam-groove e, the toggle ecomprising the links 6 e, the first of which is pivoted to thestationary support e at its lower end, and the second of which isconnected at its upper end with the slide-head e", and the links of thetoggle are connected with an arm of the lever e by means of the link 6The slide-head c has a bearingin the bracket e, and the toggle-head E isvertically adjustable on the slide head by screwing thereon. (See Fig.2.)

This construction or organization of jacks and attaching devices allowsa number of jacks to be moved successively into operative position andenables a saving in time to be effected, which is of very considerableimportance in the operation of themachine, as it permits the operator toutilize the time which is otherwise of no account in removing thefinished shoe from a jack moved out of position and the placing of anunheeled shoe upon a jack about to be moved into position; or, if anassistant be employed, it enables one to remove the work and the otherto place it, and to thus increase the capacity of the machine veryconsiderably.

I would say that it is not essential, so far as the material features ofthe invention are concerned, that each jack be movable horizontally uponthe head D, as the head itself may be placed in linewith the templet andprovided with a vertical movement.

The trimming apparatus Gis represented as placed below the templet A andin a line therewith, and so that it may operate to trim or shave anattached heel simultaneously with the attaching of a heel to anotherboot or shoe by the heel-attaching devices above specified.

While I have shown the trimming mechanism as placed below theheel-attaching devices, I would say that I do not confine myself to thislocation, as it may be placed upon one side thereof, in which eventsupport for the jacks is organized to turn upon a horizontal plane. Iprefer, however, when a jack rotating on a vertical plane is used tolocate it be tween the jack and the nailing device, as indicated, as itmakes a more compact construction, and because the skivings and chipsfrom trimming are made below the principal working parts of the machineand cannot get into them, to interfere with their ready operation, andbecause it is more out of the way.

The trimming devices which I have represented are the well-known McKaydevices described in various patents granted to Charles H. Glidden andused upon the heel-attaching machine known as the McKay heel-attachingmachine, and it is unnecessary to more than briefly say that theycomprise a knife, G, which is carried by a block, 9, which is caused tobe moved about the heel, and is guided in part by camtracks and in partby suitableforms or guides. The operalivemechanism differs from theMcKay in that the sprocket-wheel g for rotating the k nife-carry ingblock is revolved by means of a larger sprocket-wheel, g, and by thechain G, which connects the two sprocket wheels. The sprocket-wheel g isarranged upon a pivotor post, 9*, and has a forward-and-back movementcommunicated to it by means of the cam 9 upon the vertical shaft a. Thiscam has a cam-groove, 9 which is connected with the sprocket-wheely bymeans of a lever, 9 which is pivoted at y and which is connected by alink, 9", with the cam-groove, and by thelink 9 with the sprocket-wheelgfland a partial rotation forward and back of this sprocket-wheel 9causes the knife-blockto be rotated very nearly an entire revolutionabout the heel of the boot or shoe and to be returned to its originalposition.

There is attached to each jack, spindle, or post a boot or shoe holdingand protecting device,H,which is movable there\vith,and which is similarin construction to that described in the said patents and found in thesaid Me- Kay machine. I would say, however, that, so far as the broadfeatures of this invention are concerned, I do not confine myself to thespecial mechanism herein described for tri mmin the heel.

The sprocket -wheel 9 and the cam and knife-block are supported upon aspindle, g,

ICC

which has a bearing in the bracket g, (see Figs. 2 and 4,) and itextends below said bracket and its end rests upon the block 9, which iscarried in the front end of the lever g, and in relation to which it hasa vertical movement in opposition to the spring g, the front end of thelever having a hole of sufficient size to receive the block g" andspring The lever g is pivoted at 9", and is operated by the cam 9" uponthe shaft a,having a cam-groove, g, and its office is to press or movethe lower heel-trimming form, 9, and

the knife-block upward vertically against or in relation to the heel ofa boot:or shoe upon the starting of the machine, and to maintain them inthat position during the trimming of the heel.

The front end of the lever always has the same extent of movement, andfor this reason I make the connection between it and the spindle g ayielding one,in order that the heelform and knife-block maybe alwaysmoved to any desired relation to the heel-blank, regardless of itsheight, the block 9 yielding with the spring g to allow this to takeplace.

The spindle g of course is made square, and fitsa square hole in thebracket 9, to preventits being turned.

In operation the operator preferably stands at the right side of themachine, the boot or shoe to be heeled and trimmed is mounted upon thelast or work-support, the first or second last or work-support to theright of the templet facingthe machine. The last or worksupport isthenoperated to move or bring the boot or shoe into position beneath thetemplte A, and the machine is then set in operation. The jack-spindle ofthe last or work-support, which is in position, is then moved upward,compressing the heel-blank, which has previously been moved intooperative position beneath the templet, solidly against the same, theheel-blank is perforated, the attachingnails fed and driven, the toplift fed, and the heel breasted automatically, as described in the Smallmachine. Meanwhile the operator has been placing another boot or shoeupon the next last or work-support in order, and upon the completion ofthe attaching and breasting of the heel of the first boot or shoe thejack-support is turned to bring the second boot or shoe into position,and the machine is operated as before.

If the trimming apparatus be not used, then the heeled boot or shoe maybe removed from the last or work-support by a boystanding upon the leftof the templet; or the jack-support may be rotated and shoes presentedin successive order to the nailing devices until the shoe first nailedreaches the operator, when he then removes the same and substitutesanother, and continues to operate in this manner. Y

When the trimming mechanism is employed,

the heeled boots or shoes are advanced in successive order until they.reach the trimming mechanism, and after the first one in order hasreached itthe operation of the machine is as follows:

Upon the starting of the machine a heel is attached to one boot or shoe,while the trimming mechanism is caused to be automatically operated tosimultaneously trim the heel previously, attached to another boot orshoe. The rotation or movement of the jack-support having simultaneouslymoved into operative position, one boot or shoe beneath theheelattaching devices, and another boot or shoe into operative positionin relation to the heeltrimming devices, it is desirable that the heelshould be under some degree of compression 7 during the trimmingoperation, although, as a I would say that I do not confine theinvention to the employment of ajack-support movable upon a verticalplane, because it may be movable upon a horizontal plane, if desired;but I prefer the vertical plane, because it has some advantages whichthe organization employing a jack-support movable upon a horizontalplane wouldnot possess.

The advantages of the invention arise, first, from the rapidity withwhich the work may be presented and removed from the heel-attachingdevice; second, from the saving in time which is obtained by thesimultaneous attaching of one heel and the trimming of another bythesame mechanism; and, third, by the organization of themachine, whichdisassociates the heel-trimming mechanism from the nailing devicestosuch an extent that the construction is simplified and the partsof theheel-trimming devices made more accessible, and the place of trimmingremoved from the place of nailing, so that the scraps, dust, andskivings cannot interfere with or check the nailing devices and the fineorganization of the nailing mechanism permitted.

I would say in this connection that I am aware that it'is not new tocombine in one organization a heel nailing and trimming mechanism of apeculiar organization, which attaches what is known as a loaded heel andthen trims it as successive operations. not aware, however, that therehas been any heel attaching and trimming machine organized whichinvolves the automatic presentation of the heel-blank and top lift toattaching devices and the useof attachiugdevices which involve thecompression of the heelblank upon the soles of the boot or shoe, theprick- I am.

IIO

ing of the holes therein after the heel-blank has been so compressed andthe driving of the attaching-nails; and I would further call attentionto the factthat as the attaching of one heel and the trimming of anotherattached heel arev simultaneous operations, a saving in time isaccomplished over the operation of a .ma-

chine which first attaches loaded heel-blanks and top lifts and thentrims the same heel.

Having thus fully described my invention,
